I just downloaded the trial and I have a really stupid question.
Yesterday at Siggraph, numerous times I saw demonstrators display interactive preview renders by drawing out a box around a region. But I can’t figure out the proper mouse/keystroke combination. Or perhaps I’m doing something else wrong.
I don’t even know what XSI calls this so that I could look it up in the help.
Thanks for your help and please excuse my ignorance.
EDIT: Just figured it out, I think. Q for region tool.
